川西北高原沙区沙化治理区划与治理对策研究
|
摘要
对川西北草地沙化影响因素进行分析,采用图形叠置法叠加气候图、植被区划图、沙化土地分布图,首次确定了川西北高原沙区的具体范围。在此基础上,以地质和地貌为主导因子,结合沙化土地分布现状,将川西北高原沙区划分为3大治理区,分别为:(1)石渠色达丘状高原沙化治理区;(2)若尔盖红原平坦高原沙化治理区;(3)理塘巴塘高山山原沙化治理区。同时,针对各区沙化特点,提出相应的沙化防治战略对策,为川西北防沙治沙工程顺利实施提供科学参考。
The influencing factors of grassland desertification in Northwest Sichuan were analyzed by the graphic overlay method of superposition climate map,vegetation map and desertification land distribution map,and the specific range of desert area was determined in Northwest Sichuan Plateaus. On this basis,the sandy areas in Northwest Sichuan Plateau were divided into 3 management zones with geology and geomorphology as the dominant factors in combination with the distribution of desertification land. The first management zone was Seda-Shiqu hilly plateau desertification area. The second was Ruoergai and Hongyuan flat plateau desertification zone. The last was Litang and Batang mountain primary desertification zone. The strategy of desertification prevention and control measures was proposed according to the characteristics of desertification. This prevention and control measures were in the hope of providing scientific reference for the smooth implementation of desertification control projects in Northwest Sichuan.
